This comment makes no sense because the Fourth doesn't apply to data/information that you've surrendered to the DMV and that the DMV owns.
Precisely from the same Wiki article that you linked: "...courts have found that a person does not possess a reasonable expectation of privacy in information transferred to a third party...".
So, the right "...to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures..." doesn't apply, here, whatsoever. The reason that the DMV can sell the data is a direct effect of the fact that they own the data that you've surrendered for the privilege of driving.
In order for your reference to have any standing, jurisprudence must first be reversed and that seems a dauntingly monumental and nigh-impossible task.
It doesn't mean or infer that I think it's a "good" thing (hint: I do not) but to simply dismiss it as being protected by the fourth negates the very premise that has already been established that it isn't (as in this case, with the DMV).
